I had IV Zofran this pregnancy, but with my DD I had a pump until 20 weeks. I also slowly weaned off it. I was terrified, but lowering the dosage slowly every 3-4 days until it was at its lowest dose seemed to work for me. I turned it off at 20 weeks exactly when I was only getting 12mg/day through the pump. I was terrified, as it had become a security blanket of sorts for me, but I knew it was time to try and get off of it. I then switched to oral zofran as needed, but found I didn't need it much. This pregnancy I did the same thing weaning off the IV Zofran and I'm still taking oral Zofran as needed, but I'm functioning fairly normally again.(I threw up yesterday morning, but felt ok afterwards....having an empty stomach after sleeping at night is a big nausea/vomiting trigger for me). I hope it goes well for you too!
